NHTSA Complaint #10538196 — 2011 BMW X3

A QUICK ACCELERATION FROM ZERO, AT ABOUT 25 MPH THERE WAS A LOUD NOISE FROM THE ENGINE. IT SOUNDED LIKE A SPRING BEING UNWOUND. NO LIGHTS CAME ON, HOWEVER I CALLED SERVICE CENTER AT DEALERSHIP WHERE I PURCHASED IT. I WAS TOLD IF NO WARNING LIGHTS ON, THEN EVERYTHING MUST BE OK. A FEW MINUTES LATER THE ENGINE LIGHT CAME ON AND A WARNING WAS DISPLAYED ON THE SCREEN: "DRIVE MODERATELY. MAXIMUM DRIVETRAIN OUTPUT NOT AVAILABLE. HAVE YOUR SYSTEM CHECKED AT YOUR SERVICE CENTER." I CALLED BACK TO SERVICE CENTER AND WAS TOLD IT WAS SAFE TO DRIVE HOME AS IT WAS IN LIMP MODE. CALLED BMW ASSIST AND THEY CAME AND GOT VEHICLE. ONCE AT SERVICE CENTER THEY STATED THE CLAMP HOLDING THE AIR INTAKE FOR THE TURBO HAD COME OFF. THEY PUT CLAMP BACK ON. *JS
